4 Claims.

The present invention relates to portable lamps, and is moreparticularly directed toward portable floor lamps having auxiliarylighting means to render the shade of the lamp luminous.

5 The present invention contemplates introducing into the usual columnof a semi-indirect floor lamp a short distance below the shade means fordirecting a light of low intensity toward the shade from underneath. Incarrying the present inven- 10 tion into practice it has been foundconvenient to provide the lamp standard or column with a harp whichcarries a secondary lamp socket and lamp bulb and to surround the samewith an opaque enclosure having a diffusing cover 15 through which thelight rays can pass and fall on the inside of the shade.

The accompanying drawing shows, for purposes of, illustrating thepresent invention, an embodiment in which the invention may take 20form, it being understood that the drawing is illustrative of theinvention rather than limiting the same.

In this drawing:

Figure l is a perspective view of the upper part 25 of a floor lamp; and

Figure 2 is a vertical sectional view at an en-,

larged scale.

The lamp standard employs a pipe l and an outer ornamental tubing H asusual. A com- 30 bined hickey and harp i2 is threaded on to the top ofthe pipe l0 and against the tubing II. This combined hickey and harpsupports a small switch controlled lamp socket I3 adapted to carry alamp bulb l4 and has two arms l5 and Hi to 35 accommodate the socket andlamp bulb. These arms come together at the top as indicated to form aboss ll which is threaded as indicated at I8 to receive a coupling I9for the head 20 of the lamp. This head supports the usual diffusing 0bowl 2|, bulb 22 and shade 23.

A diffuser 24 which may be of glass or suitable plastic is supported onthe boss I? and is adapted to fit against the upper end of a funnelshaped closing member 25. This enclosure may be made 45 of sheet metaland is supported on a collar 26 threaded on the outside of the combinedhickey and harp I2.

When the lamp M is lighted and the main lamp 22 extinguished the lightrays fall on the 50 inside of the shade 23 rendering it dimly luminous.When the main lamp 22 is lighted the structure forming the supplementallight source may be lighted or not. In either case it adds an ornamentaltouch to the column of the lamp 55 and its function as a supplementallighting unit is not apparent to the casual observer.

It is apparent that, within the scope of the invention, modificationsand different arrangements may be made other than is herein disclosed,and the present disclosure is illustrative 5 merely, the inventioncomprehending all variations thereof.

What is claimed is:

1. A lamp having a lamp head comprising a body, a primary light sourcecarried thereby and a downwardly and outwardly flaring shade about theprimary light source, a coupling extending downwardly from the body, acurved arm secured to the lower end of the coupling and having its lowerend directly under the coupling but spaced therefrom, a secondary lampsocket and lamp bulb supported by the lower end of the arm and disposedbetween the ends of the arm, a substantially horizontal light diffusingcover of substantial area above the secondary lamp bulb andnon-removably secured between the top of the arm and the bottom of thelamp head, a vertically movable, opaque housing normally disposed aboutthe secondary socket and lower part of the arm and extending downwardlyfrom the periphery of. the cover so as to conceal the arm, secondarylamp socket and bulb, and means for detachably securing the housing atits lower end in such position or for permitting lowering it to giveaccess to the secondary lamp bulb. 30

2. In a portable lamp, in combination, a tubular standard, an aperturedhickey near the top thereof so that wires may be passed outwardlythrough the aperture, an upwardly extending arm having its intermediateportion offset from the standard axis and its upper end in the axis,

a lamp head secured to the upper end of the arm and including a primarylight source and a reflector, a shade about the reflector, a secondarylamp socket and lamp bulb secured to the hickey and disposed between theends of the arm, and

an enclosure for the secondary source including a substantiallyhorizontal, centrally apertured, diffusing cover, means at the upper endof the arm for fixedly supporting the diffusing cover, the diffusingcover being of substantial area to transmit light upwardly under theshade for lighting the shade, a vertically movable, opaque housingnormally disposed about the secondary 5o socketand lower part of the armand extending downwardly fro-m the periphery of the cover so as toconceal the arm, secondary lamp socket and bulb, and means fordetachably securing the housing at its lower end in such position or fora secondary lamp socket and lamp bulb secured inside the harp, acentrally apertured light transmitting cover supported at the top of theharp, an opaque housing extending from below the hickey aperture up tothe edge of, the diffusing cover, a housing supporting ring threadedonto said member, a coupling secured to the top of the harp andextending through the difiusing cover, and a lamp head having a primarylight source,

the lamp head being carried by the coupling and 10 securing thedifiusing cover in place.
